The 27-year-old actress debuted her new blonde do last week in an Instagram photo taken at the Floyd Mayweather Jr. vs. Manny Pacquiao boxing match. And as much as we loved her month of colorful styles, it seems the blonde may be sticking around for awhile. With all that dyeing in a such a short amount of time, we don’t blame her! But we do wonder how her son, Luca, feels about her new blonde do, as he’s had lots of opinions on how she wears her hair these days.

“Luca is very particular about how he likes my hair,” she revealed to Ellen DeGeneres. “There’s absolutely no buns on my head, no ponytails. I’ll have a ponytail and he’s like, ‘Um, hair down, mom. Hair down, please.’ At least he knows what he likes … He saw [my mermaid hair] and he’s like, ‘Is your hair green, mom?’ And I’m like, ‘That’s right, it’s green.’ And he’s like, ‘Wow.’ “
